990r (411088141) String Trimmer
740R 2-Cycle Gas Trimmer
This item works with the following types of products:
- • Blower
- • Cultivator
- • Edger
- • Trimmer
- • Vacuum
2. Remove the old primer bulb assembly from the right cover. Disconnect old fuel lines as required.
3. Draw or take a picture of the throttle control trigger in the right cover, then remove it and the cable from the cover.
4. Remove the throttle cable from the right cover and set it to the side. It won't go far because the kill switch is still attached.
5. Removed the gas tank and all old/broken hoses/parts.
6. Installed the fuel line in the bottom of the tank. (This requires pulling the filter hose connection through the small hole in the bottom of the tank from the inside. Do not use pliers. Just feed the end of the hose through the hole and apply a steady pull to the hose and wiggle it around. The piece will pull through without breaking anything.)
7. Install the new return fuel line (mine was blue) on the primer bulb assembly.
8. Cut a bevel on the other end to make it easy to feed it into the side hole on the gas tank. This hose was a little long, so I had to cut about an inch off to make it fit correctly.
9. Install the fuel line (bottom of gas tank) to the connection on the cylinder side of the carburetor. This requires good light and long needle nose pliers, unless you want to remove the air filter. (this also removes the carburetor.)
10. Install the primer bulb in the right side cover with the short (clear) fuel line to the front.
11. Connect the front line (clear) to the fitting on the intake side of the carburetor.
12. Push the rear line (blue return line) into the hole in the side of the gas tank.
13. Re-install the throttle cable and trigger assembly to the right cover.
14. With the right cover in place, but not screwed down, and without replacing the left cover, add fuel to the gas tank and check for leaks.
15. Press the primer bulb several times to be sure it is operating properly and there are still no leaks.
16. If all is good, replace the left cover and install all the mounting screws.
Note: I had not used my blower for about 5 years, so I had to do the fuel/air mix setup found in the manual and replace the spark plug. Runs like a dream and no gas leaks.
2) Remove fuel and fuel return lines
3) Remove fuel filter from inside of gas tank
4) Thread small gauge wire up into gas tank through fuel supply hole
5) Insert hose end of new fuel filter hose over the wire in the gas tank
6) Feed fuel hose down along the wire. Wire acts as a guide to line up the new hose.
7) Pull wire and hose through hole in tank
8) Seat fuel filter
9) Discard wire and connect all hoses
10) Replace carburetor / muffler cover
Watched a YouTube video on replacing fuel lines and general tune up...looked up my brand/model on ereplacementParts.com and they had all the parts listed for any repair i might have...i selected the parts mentioned in the video and paid for them in the easy check out... they were delivered within a couple days...I watched the video again and re-assembled my parts and the trimmer started right up...the next day i was trimming about an acre of weeds n grass..
This was my first time using ereplacementParts.com. For me everything went great..i highly recommend them to anyone trying to repair your own equipment...
Pulled return line off spigot on primer using screw driver blade to gently ease line off
Clipped end of replacement line on angle to ease fitting then pushed into fuel tank.
Cut to other end to length and the pushed other end on to spigot on fuel primer
